Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tien thanh » tien thinh, tran thanh, den thanh
cua nhung » va nhung
anh mang » hanh mang, anh bang, anh dang
mang cua » manh cua, dung cua, ban cua
cong dan » cong san, cong tan, huong dan
chan ban » can ban, chan nan, chan doan
chat ban » nhat ban, chat ran, cua ban

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((tien thanh) OR (tieng anh)) - anh mang cua nhung cong dan ((chan ban) OR (chat ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((tien thanh) or (tieng anh)) - anh mang cua nhung cong dan ((chan ban) or (chat ban))*.
